Abstract

In this paper, the effect of the position of the pin relative to tool shoulder has been investigated in the process of friction stir welding on aluminum 5083. Firstly, the preparation of the process was performed that included tool, workpiece fastened to dynamometer by special fixture, and milling machine. A test was performed by a tool with pin coaxial with the axis of tool shoulder in this process. So, the tool entered the edges of joint location and moved along the joint line. Force in joint region was measured during the process. Then, the parameters of the shape and the position of tool pin changed and joint test was performed. The shape of the tool changed by offsetting the axis of tool pin relative to the axis of tool shoulder with different designs, and the results of welding forces were considered.
